Patent ES-476329-A1 (ES)
Title: Internal combustion engine with exhaust gas recirculation
IPC: F02B75/18
Filed: 1978-12-26
Abstract: This disclosure relates to a turbocharged internal combustion engine. The exhaust manifold of the engine is divided into sections, and the engine exhaust from one of the sections is recirculated to the intake manifold. The engine cylinders that feed the EGR exhaust manifold section alternate in the engine firing order with the other cylinders, thereby providing a substantially uniform flow of exhaust gas to all of the cylinders. The turbine of the engine turbocharger is divided into two sections, one having a smaller flow area than the other. The turbine section having the smaller flow area is connected to receive the exhaust gasses from the exhaust manifold section that also supplies the EGR.

Title: Data processing apparatus with intersegment call.
IPC: G06F9/38
Filed: 1982-09-15
Abstract: A computer architecture is disclosed which permits intersegment program calls with associated selective allocation of data segments of varying lengths.

Abstract: A unit cell for a prefabricated semiconductor chip, to be converted into an array of logic gates by selective metallization, comprises two complementary pairs of MOSFETs occupying respective quadrants of a rectangular substrate area, with external gate contacts disposed in respective headers extending along the minor sides of the rectangle. Each header further contains two external channel (source or drain) contacts which with the two external gate contacts form a group of four input/output contacts. Two metallic strips serving as supply buses, parallel to the minor sides, are separated from the two headers by relatively narrow substrate zones so as to define a relatively wide central region between them. The external gate contacts of two diagonally opposite MOSFETs are interconnected by a strip of polycrystalline silicon crossing the supply buses, each of these buses being also crossed by a respective polysilicon strip linking the other external gate contact of the proximal contact group with an internal gate contact located in the central region. The two external channel contacts in each header, which are disposed near the corners of the cell area, are paired with respective internal contacts also located in the central region on correspondingly doped substrate portions, as are two other internal channel contacts each common to a respective transistor pair and located in an inner terminal section of its respective transistor pair which is separated from the associated outer terminal sections thereof by the polysilicon strips running between the associated external and internal gate contacts. A further polysilicon strip extends along one of the major sides of the cell area to facilitate certain intercell connections.
